To all whom it may concer-a:

Be it known that l, EUGENE lllinrnmis, a citizen of the United States, and a resident of Chicago7 in the county of Coeli and State of illinois, have invented certain new and useful Improvements in laper-Coating Mw chines, of which the following is a specification.

rlhis invention relates to a coating apparatus for coating or painting sheets of paper or analogous material, and in general construction is similar to that set forth in my prior patent, Nlo. 773840.

Among the salient objects of my invention are to provide a construction whereby the pigment or natural coloring` matter may be universally and evenly applied to the paper; to provide a construction which permits the paper to be evenly coated with a minimum and definite number of sweeps of the brush; to provide a construction which prevents binding of the brush wheels upon their respective rails and at the saine time maintains and insures a movement of the brush at right angles with the sides of the table; and in general to provide simple and efficient construction of the character referred to.

The invention will be readily understood from the following description, reference being had to the accompanying drawings in whiehlligure 1 is a side elevation of my device, parts being broken away to reduce the size of the drawing and to show the interior of the color tank. Fig. 2 is an enlarged crosssectional detail, showing the manner of supporting the brush and hangers on the trolley head. Fig. 3 is a transverse sectional view taken through lines of Fig. 2 and .looking in the direction of the arrows. it is a perspective vie-w of the brush, showing diagrainmatieally the manner of arranging the guiding belt.

Referring to the drawingsy 1 designates the table having a horizontal top 2, upon which the paper 2 to be coated is placed. ln order to give the table sufficient stability, it is provided at either side with cross snpports 3 3 and side rails Lll, suitably secured to the table legs 5 5. The bottom rails 5 further add to its stability. it one end of the table is provided ay fountain or color tank 7 for the paint or coating fluid, into which the brush end is adapted to he immersed. @n the top of the table at the opposite end is secured a metal strip 3 and bent .inwardly at its top to forni a stop plate against which the paper lies flush while it is being coated. rEhe brush 9 .is secured to the traveling carriage which is supported above the table and is adapted to travel across the track rails 10-10 which extend along either side of the table. it one end, the rails 10 are bent downwardly7 and secured to the plate 7 which serves also to support the fountain 7. rt their other ends, the rails are supported by standards 11 secured to the table.

llescribing new the. brush carriage proper7 designates a trolley head which extends transversely7 of the tableand has side plates which form depending jaws 13, between which the brush head is clamped by suitable through bolts 14. To each end of the trolley head is pivotally secured a triangular truck plate 15 by means of the supporting rod 15 extending through space plates 1S" secured in the head 12 seen clearly in ll Upon each plate 15 are journaled two upper wheels 16 adapted to ride in the upper sides of tneir respect-ive traer rails. nl lower wheel 17 is journaled upon the stud 1T which is mounted to niove vertically in a slide way (not shown) formed in its respective truck plate 15. ln order to keep the lower wheels in constant bearing with their respective track rails, each stud 1? is provided with a spring 19 secured at one end of the stud and at the other to an extension of the rod 1G. lt will thus be seen tnat the wheels can freely travel upon the track rails but at the saine time the ends of the trolley head are kept in firm bearing with the rails.

t the sides of the coating table, are secured gutters for receiving any drip or overiiow of the coating iiuid during the operation of the apparatus.

Heretolore in a device of this character difliculty has been experienced in preventing binding of the truelr wheels upon the rails and also in securing a traveling of the brush at exact right angles to the sides of the table. To overcome these defects and as an important feature of inf; inventioin l provide an endless belt fastened to either end of the brush and trained over a series of belt sheave l/lescribing this ciuistrnetion in detail7 vertieally-disposeil sheaves Q3-23 are ln order that the lower sheaves may be approximately beneath their respective upper sheaves, they are journaled to brackets 2S secured to the legs .5, as seen clearly in Fig. l. ln a horizontal plane approximately coincident with the lower peripheries of the sets of lower sheaves and at right angles thereto, are journaled, on brackets 32, four sheaves Q-30 and 31-31, two at each side of the table, as seen clearly in Fig. il. The outer part of the periphery of each of the horizontal sheaves coincides with the lower part oit the periphery of each ot their respective vertical sheaves.

lescribing` now the manner in which the endless belt is trained over the sheaves and starting for example with pulley 23, the belt is trained from the latter over sheaves 2l and 2G to horizontal sheave 31, thence across to sheave 30, and around sheaves 25 and to sheaves 24, thence downwardly to sheave 2G over sheave 31 across to sheave 30 and up over sheave Q5 back to sheave 23. r'he upper laps of the belt are integrally connected to the truck plates 15 by suitable eyes 553-33 which are so arranged that the eyes may easily ride by the upper sheaves 23-23 when the brush is being immersed in the liquid. From the arrangement of the belt described it will be seen that as the brush moves across the paper it will at all times be at exact right angles to the sides o1L the table but will have oscillatory movement inasmuch as the truck plates l5 are pivotally connected to the trolley head 1Q. frs hereinbefore stated this arrangement of the belt also prevents binding of the 7heels upon thei respective rails.

lllhile l have shown and described a preferred embodiment ot the invention, yet it will be understood that the details may be somewhat modified without departing from the spirit of the invention;
